HEADLIGHT.

, Application filed. September 21, 1921. Serial No. 502,149.

To all whom it may concern:

Be it known that I, VVILLIAM S. ELSEY, a citizen of the United States,residing at Cairo, in the county of Alexander and State of Illinois,have invented certain new and useful Improvements in Headlights, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain improvements in headlights, and itisan object of the invention to provide a novel and improved device ofthis general character having a single light source, together with meanswhereby the rays emitted from said source are directed both forwardlyandrearwardly, the rearwardly directed rays serving to illuminate the sideof'the vehicle to expose its lines to prevent sideswiping and also tolight up its lines to enhance the beauty of the vehicle when travelingafter nightfall.

Another object of the invention is to provide a novel and improveddevice of this general character embodying a single light source, the.lower rays emitted from said source being forwardly directed while theupper rays emitted from the source are bended to throw rearwardly, theupper portion of the device serving as a means to prevent the forwardlydirected light rays from blinding persons in advance of the car and thusfully complying with the traflic regulations.

The invention consists in the details of.

7 construction and inthe combination and arembodiment of my invention;

rangement of the several parts of my improved headlight whereby certainimportant advantages are attained and the device rendered simpler,lessexpensive and otherwise .more convenient and advantageous for use,

as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accom panyingdrawings, wherein:

igure 1 is a view in front elevation of a headlight constructed inaccordance with an Figure 2 is a view in side elevation of the device asherein disclosed; and

Figure 3 is an enlarged vertical sectional view taken through myimproved device.

As disclosed in the accompauyin drawings, my improved headlightcomprises two sections A and B, each of which is concavoconvex andsubstantially of the form of a quarter sphere. The rear face of thesection A and the forward face of the section B compriseverticallyalined lenses or glass panels 1 while the upper face of the section Band the lower face of the section A comprise the substantiallyhorizontally alined lenses or glass panels 2.

Blythis arrangement, the section A of the hea light is positioned aboveand forwardly of the section B so that the section B provides means forilluminating ahead of the ear to which the headlight is applied whilethe section A operates to direct the light rearwardly.

The headlight is adapted to be supported in applied position inanydesired manner such as the bracket 3 indicated in fragment in theaccompanying drawings.

The upper rear marginal portion of the section B of the headlight and atthe transverse center thereof is provided with a light source 4: hereindisclosed as an electric lamp, the same being adapted to be operated bya suitable source of electrical energy carried by the vehicle.

\Vhen the source 4 is illuminated, the beams of light will extendforwardly of the vehicle through the lens or glass panel 1, the innerwall of the section B serving as a reflector to assure such throwing ofthe light. The light *from the source 4 will also pass through thelenses or glasses 2 and be bended and thrown rearwardly by the internalreflecting wall of the section A whereby the side of the car or vehiclewill be efiectively illuminated in a manner to prevent sideswiping andalso to clearly bring out the lines of the car so that the beauty of thevehicle will be enhanced and particularly when driving after nightfall.

5 denotes a hood pivotally supported for swinging movement and which,when in full open position, overlies the upper section A but which isadapted to be swung rearwardly to partially close the space between therear face of the upper section A and the top face of the lower section Band which is particularly desirable in order to prevent the lightextending upwardly into the car and thereby blinding the driver. Thehood 5 may also be dropped down to shut off the light from beingprojected forwardly, in its entirety or in part.

The relative arrangement of the sections A and B causes the uppersection A to serve as a shield to prevent the light from blindingpersons in advance of the car.

The upper marginal portion of the section B immediately adjacent thelight source 4 is provided with a supplemental metal reflector 6, saidreflector being of a width substantially equal to the major width of thesource 4 and extending upwardly and forwardly. The reflector 6 is setinwardly of the section B a distance sufficient to permit the desiredclosing of the hood 5. This reflector 6 serves to direct a portion ofthe light rays against the reflecting surface of the section A which, inturn, will recast the light rays partly to the rear and partly down ontothe reflecting surface of the section B and then forwardly. Thisreflector 6 thereby serves effectually to prevent the light rays fromthe source i being directly projected upwardly and rearwardly.

From the foregoing description it is thought to be obvious that aheadlight constructed in accordance with my invention is particularlywell adapted for use by-reason of the convenience and facility withwhich it may be assembled and operated, and it will also be obvious thatmy invention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in"'carryingout my invention in practice except as hereinafter claimed.

I claim:

l. A headlight comprising two reflector sections each having a concaveface substantially in the form of a quarter sphere, the concave faces ofthe sections being opposed, one of said sections being positioned aboveand in advance of the second section, the upper section having itsforward face downwardly disposed and its rear face rearwardly disposed,the forward face of the lower section being forwardly directed and therear face of said lower section being upwardly directed, and a lightsource arranged within the lower section of the headlight adjacent toits rear face.

2. A headlight comprising two reflector sections each having a concaveface substantially in the form of a quarter sphere, the concave faces ofthe sections being opposed,

one of said sections being positioned above and in advance of the secondsection, the upper section having its forward face downwardly disposedand its rear face rearwardly disposed, the forward face of the lowersection being forwardly directed and the rear face of said lower sectionbeing upwardly directed, a light source arranged within the lowersection of the headlight adjacent to its rear face, the rear face of theupper section and the forward face of the lower section being in radialalinemcnt and substantially vertically disposed.

3. A headlight comprising two reflector sections each having a concaveface substantially in the form of a quarter sphere, the concave faces ofthe sections being opposed, one of said sections being positioned aboveand in advance of the second section, the upper section having itsforward face downwardly disposed and its rear face rearwardly disposed,the forward face of the lower section being forwardly directed and therear face of said lower section being upwardly directed, a light sourcearranged within the lower section of the headlight adjacent to .its rearface, and a reflector carried by the. lower section of the headlightextending upwardly and forwardly toward the upper section and overlyingthe light source.

i. A headlight comprising'two reflector sections each having a concaveface substantially in the form of aquarter sphere, the concave faces ofthe sections being opposed, one of said sections being positioned aboveand in advance of the. second section, the upper section having itsforward face downwardly disposed and its rear face rearwardly disposed,the forward face of the lower section being forwardly directed and therear face of said lower section being upwardly directed, a light sourcearranged within the lower section of the headlight adjacent to its rearface, and a swinging hood supported by the headlight, said hood when inone position overlying the upper section and when in a second positionpartially closing the space between the rear face of the upper sectionand the rear face of the lower section.

In testimony whereof I hereunto affix my signature.

WILLEAM S. ELSEY.
